Cylinder Pressure-Relief Devices钢瓶减压装置General概述Pressure-relief devices are installed on most cylinders to prevent the rupture of a normally pressurized cylinder when it is inadvertently exposed to fire or high temperatures. There are many types of pressure-relief devices; each has a designated use. Types of pressure-relief device designs include fusible plugs, rupture disks, rupture disks with fusible metal backing, and spring-loaded relief valves.大多数钢瓶上安装有减压装置，以防止当无意中暴露于火或高压时正常加压的钢瓶破裂。

减压装置有许多种类型；每种都有指定的用途。

减压装置的设计类型包括易熔塞、破裂盘、带易熔金属衬里的破碎盘和弹簧减压阀。

This Safetygram identifies the pressure-relief devices used to provide cylinder protection for various compressed gases. The specific pressure-relief device designated for a compressed gas cylinder depends on many factors, including the type of gas, the Department of Transportation (DOT) rated service, test pressures of the cylinder, and the cylinder size.本安全程序鉴别为各种压缩气体提供钢瓶保护的减压装置。

指定用于一种压缩气体钢瓶的专门减压装置取决于许多因素，包括气体类型、交通部（DOT）额定的寿命、钢瓶的测试压力和钢瓶大小。

The Compressed Gas Association (CGA) lists the pressure-relief devices to be used on specific products in their Pamphlet S-1.1“Pressure-Relief Device Standards Part 1:Cylinders for Compressed Gases.” DOT regulations require compliance with this document for the selection and use of pressure-relief devices to be used on compressed gas cylinders.在他们的手册S-1.1“减压装置标准第一部分：用于压缩气体的钢瓶”中列出了用于专门产品的减压装置。

对于用于压缩气体钢瓶的减压装置的选择和使用，DOT的规范要求同这个文件相一致。

CAUTION: Pressure-relief devices do not permit the user to exercise any less care in following proper handling, use, and storage procedures for cylinders.警告：减压装置不允许用户在遵守正确的钢瓶操作、使用和储存程序方面有任何的掉以轻心。

Types of Cylinder Pressure-Relief Devices钢瓶减压装置的类型The CGA has identified several types of pressure-relief devices:压缩气体协会已经鉴定了减压装置的几种类型：Type CG-1: The Rupture Disk DeviceCG-1型：破裂盘装置A rupture disk device is a nonreclosing pressure-relief device actuated by static pressure and designed to function by the bursting of a pressure-containing disk. The disk is the operating part of the device. It is a flat disk, typically made of metal, designed to a specification that will allow it to burst at a predetermined pressure to permit the release of gas. Rupture disks relieve overpressure in cylinders that may result from an external fire or from overfilling. The burst pressure of rupture disks may not exceed the minimum DOT-required test pressure of the cylinder, which is generally 5/3 of the cylinder service pressure. Some exceptions to this rule are:破裂盘装置是一个非重闭减压装置，它由静压力启动，通过容压盘的破裂发挥作用。

破裂盘是装置中的工作部件。

它是一个平坦的盘子，多数用金属制成，设计得允许它在预定的压力下破裂，从而让气体释放。

破裂盘释放钢瓶内可能源于外部着火或过量灌装的过多的压力。

破裂盘的破裂压力不能超过DOT要求的钢瓶的最小测试压力，该压力一般是钢瓶工作压力的5/3。

这个规定的一些例外是：•The burst pressure must not exceed 4500 psig for DOT-3E or CTC-3E specification cylinders.对于DOT-3E或CTC-3E规格钢瓶，破裂压力不能超过4500 psig。

•The burst pressure must not be less than105% of the cylinder test pressure or greater than 80% of the minimum burst pressure for DOT-39 cylinders. 对于DOT-39钢瓶，破裂压力不能小于钢瓶测试压力的105%，或者大于最小破裂压力的80%。

The pressure rating of the disk is typically stamped onto the face of the device.破裂盘的额定压力一般印在装置的正面。

Type CG-2: Fusible Plug Device Rated at 165°FCG-2型：额定在165°F的易熔塞装置The fusible plug device is a nonreclosing pressure relief device designed to function by the yielding or melting of a plug of fusible metal. The type CG-2 plugs use an alloy that yields at a temperature not exceeding 170°F, nor less than 157°F (165°F nominal). These devices are not suitable for service pressures exceeding 500 psig. Pressures above 500 psig may cause the fusible alloy to extrude and eventually release the product.易熔塞装置是一个非重闭减压装置，通过易熔金属制成的塞子的变形或熔化发挥作用。

CG-2型塞子使用一种合金，该合金在不超过170°F和不小于157°F (标称值165°F)的温度时变形。

这些装置不适用于超过500 psig的工作压力。

500 psig以上的压力会使易熔合金变形和最终释放出产品。

Failures from excess pressure are time- and pressure-dependent. These devices cannot be relied upon to protect from over pressurization at temperatures below their melting point.过大压力导致的失效同时间和压力有关。

在温度低于它们的熔点时，不能依赖它们来防止过压。

They are designed to protect the cylinder from over pressurization caused by exposure to excessive heat only. In the event a cylinder is exposed to fire or other sources of excess heat, the fusible plug is designed to melt and release the cylinder contents. This prevents product within the cylinder from creating excessively high pressures, caused by high external temperatures, and rupturing the cylinder. The plugs may use one of several designs to hold the fusible alloy in place. (See Fig. 2.)The temperature rating of the fusible metal is stamped into the face of the device. 它们只能防止仅仅由于接触过多的热量导致的钢瓶过压。

The pressure relief/discharge valves are CE marked in accordance with the European Pressure Equipment Directive 97/23/EC.Parker Safety Blocks are supplied in two different sizes, and are available with pressure relief/discharge valves which are suitable for flow rates up to 300 l/min at 330 bar on the largest size, ASB64. They are available with either manually- or electrically-operated discharge valves.Commissioning and maintenance of the safety block andassociated equipment must be performed by qualified personnel.12345678Accumulator Safety Blocks4Parker Hannifin plc Cylinder Division Watford, Herts.Catalogue HY07-1241/UKASB SeriesASB20ASB20 Safety BlockThe ASB20 accumulator safety block incorporates a manually-operated pressure relief/discharge valve, and is also available with an additional electrically-operated discharge valve – see pages 5 and 6. The manual-only version, ASB20 type M, is denoted by an M in the model number, see page 15, while models with the additional electrically-operated discharge valve, ASB20 type E, are identified by the letter E. Bothversions incorporate a lever-operated shut-off valve and the type SVH pressure relief/discharge valve shown on page 13.The cartridge design of the pressure relief/discharge valveallows it to be readily replaced by a valve with a differentpressure setting. The pre-set pressure, in bar, is stamped onto the identification plate and follows the model number.A handwheel allows the pressure relief valve setting to be adjusted between zero and the pre-set maximum. Where frequent or remote operation of a discharge valve is required,an electrically-operated discharge valve should be specified.The block should always be mounted as close as possible to the accumulator. For diagnostic purposes and continuous pressure monitoring, the block has two ports – M1 and M2.ASB20 Type EManually- and Electrically-Operated Discharge ValvesDimensions and Weightsxxx = pressure setting of pressure relief valve – see page 13A range of adapters is available for accumulator port A – see page 14D p [bar] = f (Q A ®T )Flow ResistanceQ [l/min]Q [l/min]Flow Resistance at DischargeASB20 Type MManually-Operated Discharge Valve D p [bar] = f (Q A ®P )e p y T A P T 1M 2M gkth g i e W r e b m u N m e t I M 022x 33M 1G G /12G /12G /149.5x x x -5T M 02B S A E022x 33M 1G G /12G /12G /144.6xx x -5T E 02B SA 012345678910010020030040050005010015020025030035005101520255 Parker Hannifin plc Cylinder Division Watford, Herts.Catalogue HY07-1241/UKAccumulator Safety Blocks ASB Series ASB206 Parker Hannifin plc Cylinder DivisionWatford, Herts.Catalogue HY07-1241/UKASB SeriesASB20Dimensions ASB20ET5 All dimensions are in millimetres unless otherwise stated.Pressure relief/discharge valve shown only in this viewMax. operating pressure p = 350 barManualPlugincluded)Accumulator Safety Blocks7Parker Hannifin plc Cylinder Division Watford, Herts.Catalogue HY07-1241/UKAccumulator Safety BlocksASB SeriesASB32/64Accumulator Safety Blocks8Parker Hannifin plc Cylinder Division Watford, Herts.Catalogue HY07-1241/UKASB SeriesASB32Dimensions ASB32MT5All dimensions are in millimetres unless otherwise stated.P r e s s u r e r e l i e f /d i s c h a r g e v a l v e s h o w n o n l y i n t h i s v i e we c u r i t y e a la n u a l i s c h a r g el )b l i n g t h e i e n t a t i o n d p i n9 Parker Hannifin plc Cylinder Division Watford, Herts.Catalogue HY07-1241/UKAccumulator Safety Blocks ASB SeriesASB3210 Parker Hannifin plc Cylinder DivisionWatford, Herts.Catalogue HY07-1241/UKASB SeriesASB32Dimensions ASB32EF5 All dimensions are in millimetres unless otherwise stated.Pressure relief/discharge valve shown only in this viewSecuritysealAccumulator Safety Blocks11 Parker Hannifin plc Cylinder Division Watford, Herts.Catalogue HY07-1241/UKAccumulator Safety Blocks ASB Series ASB6412 Parker Hannifin plc Cylinder DivisionWatford, Herts.Catalogue HY07-1241/UKASB SeriesASB64Dimensions ASB64EF5 All dimensions are in millimetres unless otherwise stated.Max. operating pressure p = 350 bar Pressure relief/discharge valve shown only in this viewAccumulator Safety BlocksASB SeriesPressure Relief/Discharge ValveASB SeriesAdapter for ASB20 Block Safety BlockAdapter for ASB32/64 Safety BlockAccessoriesReplacement Electrically-Operated Discharge ValveAll dimensions are in millimetres unless otherwise stated.ro t a l u m u c c A 1D W S L 1L 2D 3D t h g i e W g k r e b m u N t r a P G 3/4822O S I -64336135614.0-02T S E U 3/41G 1/4822O S I -55140236024.01-02T S E U 1/42G 822O S I -08642209025.12-02T S E U le d o M t h g i e W g k r e b m u N t r a P C D V 42,e v l a V y a W -2/253.010V D E ti K l a e S -VD E -K S 1D r o t a l u m u c c A t h g i e W g k r e b m u N t r a P 822O S I -2G 2.22-23T S E UASB SeriesHow to OrderPressure PortSizeASB Product TypeCode SealPage5FPM 12Code Discharge M Manual E ElectricalDischargeSeal Compound Pressure SettingCode Pressure PortTT hread F FlangeCode Pressure Setting Page5070100120140160Pre-set values for type-approved 200pressure relief valves 13210250280300330Code Size Page 20NG204-632NG327-1064NG647,11-12Cylinder Division Sales OfficesAustria Marchtrenk Parker Hannifin GmbH Tel: (7242) 569 21Fax: (7242) 569 2120Belgium NivellesParker Hannifin S.A.
